The tank is mostly good for nano tank purposes, but pictures don't really make it clear that the included lid does not cover the entire top of the tank. The feeding hole is obvious, but there is also a 1-inch gap at the back when the lid is installed. I wish it came with a plastic strip in the back to cover that space. I fortunately had some 1/8" plexiglass on hand for another project, so I was able to cut out a new lid from that. But be aware of this gap if you have potential escape artists in mind for your nano tank.
